The impacts of colonialism in Africa and Asia have never been compared in a systematic manner for a large sample of countries. This research survey presents the results of a new and thorough assessment of the highly diverse phenomenon -including length of domination , violence, partition, proselytization, instrumentalization of ethno-linguistic and religious cleavages, trade, direct investment, settlements, plantations, and migrationorganized through a dimensional analysis (political, social, and economic impacts).

" In this regard, the article by Lenski and Nolan (1984) had opened up a new avenue of research: the lon g-term effects of social-evolutionary development levels on th e modem /postcolonial econom y and society. This re search, how ever, suffered from a rather small sample and a rudimentary classification of countries into two categories of "industrializing horticultural" and "agr icultural. "
